APPARATUS FOR PRODUCING POWDERED MEAT Y'RGDUC'ifi AND THE LIZ 'JZE To all whom it may concern:

Be it known that I, JOHN C. MACLACrL LAN, a citizen of the United States, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented certain new and useful Improvements in Apparatus for Producing Powdered Meat Products and the like; and I do hereby declare the following to be a full, clear, and exact de scription of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.-

My present invention'hasfor its object to provide an improved apparatus especially adapted for reducing meat,'or the like to a powdered or finely divided dry form in which the owdered meat will contain all of the foo :onstituents, to wit, all. of the or anic and inor anicmaterial of the origina meat with all but a small per cent. of water extracted therefrom.

The present apparatus is in the nature of a modification oi the apparatus; broadly claimed in my prior Patent No. 1,301,288,0t date April 22,1919,entitledAmmratue tor granulating semi-flnid materials.

The chief novelty'in the present invention is found in the improved form of rotary extensible head from which the meat is ejected and by which it beaten into powdered form in the presence oi a hot drying medium.

The invention is illustrated in the L7(:(')H1- panying drawings wherein like charactcr.--: indicate. like parts throughout'the se aerialviews. Referring to the drawings2-- Figure l is a vertical section illustrating the invention;

Fig. 2 is a side elevation of the improved discharge head; and

F ig. 3 is a' section on the line oi Fig. 2.

The numeral 4; indicates a fragment of the upper portion of a housing through which hot air is circulated, preferabl 1 enbs'tantially as more fully illustrated in my said prior application.

The numeral 5 indicates a fran'ieworlr mounted above the housinge and on which is mounted a motor, such as an electric motor 6, the annature shaft of whichis vertically extended and equipped with a driving pulley 7. A belt 8 runs over the pulley 7 and over a smaller pulley 9 on the tubular shaft 10 that is jou'rnaled in suitable bean Specification of Iletters Patent.
